The effect of thermal ageing on low voltage cross-linked polyethylene insulated cable

This research presents some results and discusses the investigation on thermal ageing of low voltage cross-linked polyethylene (XLPE) insulated cable rated at 0.6/1(1.2) kV. This type of cable was found to experience premature degradation within three to five years of service. The objective of this...
